To all whom it may concern:

Be it known that I, JOHN Bmeos a citizen 1 of the United States, residing at an Francisco, in the county of San Francisco and State'of California, have invented new and v useful Improvements in Multiple-Disk Phonographs, of which the following is a specification.

This invention relates to a phonograph and particularly pertains to a machine of the multiple disk type.

It is the principal object of this invention to provide a phonograph adapted to automatically operate to successively play a series of phonographic records; to repeatedly play any one of said records, both operations being automatic'and produced by mechanism whlch may be actuated to discontinue the playing operation at an interval of time between the playing of the records or during the playing of'the records.

The present invention contemplates the use of a multiple disk carriage, adapted to be motor driven and to successively present records in operating relation to a driving mechanism and into register with a reproducer and its tone arm, said records and the tone arm being automatically controlled by a series of electric ush buttons.

, The invention is i lustrated by way of exarfiple in the accompanying drawlngs, in w ich Figure 1 is a view in plan, disclosing the I carriage equipped with phonographic records and furt er illustrat ng the relation of the reproducer mechanism thereto.

Fig. 2 is a view in vertical section and elevation, as seen on the line 2-2 of Fig.1, disclosing the complete operating mochanism, electric circuits.

Fig. 3 is a view in vertical section on the line 3-3 of Fig. 1, disclosing the relation.

of the driving mechanism to the disk carriage.

Referring more particularly to the drawings, 10 indicates a suitable cabinet, preferably formed of wood and in which the phonograph mechanism is disposed. This cabinet may be of anysuitable design and 1s shown in Fig. 2 as having cross members 11 and 12,. which members form the support for the electrical and mechanical mechanism. Mounted upon the member 11 are.

bearings ,13, adapted to support a carriage as well as a wiring diagram of the axle 14 in a horizontal plane and for free rotation. Disposed between these bearings and mounted upon the axle, is a disk carriage 15. Thls carriage is in reality a wheel having spokes or central webbing, around the clrcumfercnce of which a mm 16 is formed. Recesses 17 are cut in the rim at intervals and receive disk drivin wheels 18. These wheels stand tangential y to the circumference ofthe carriage and are mounted upon pins 19, extending radially through bearings in the carria e rim. The wheels 18 are intended to be frictionally driven and are secured upon the pin 19 to drive it and a phonographic disk 20 which is detachably secured to the end of the in by means of a fastening member 21. is member extends through slots formed on the outer end of pin 19 and performs an additional function in connectlon with the electrical apparatus of the mechanism, as will be here1nafter set forth.

The phonographic disks are disposed in equal spaced relation to each other around the circumference of the-wheel and are in the resent instance shown to be seven in num er. It will be understood that the dimensions of the disks and the diameter of the carriage will determine the number of disks which may be used at any one time. The rim 16 on the wheel is in constant frictional engagement with .a friction driving disk 22, more particularl shown in Fig. 3 of the drawing. This dish is mounted upon an oscillating shaft 23, which'is disposed in fixed radial relation to the carriage and may swing laterally thereof, as influenced which are appropriately pivoted to the floor I 12 and permit the entlre structure to move, as previously specified. The shaft 23 is driven from a drive shaft 27, through suitable gearing 28, interposed between the end of the shaft 27 and the vertical shaft 23.

any type of gear mg might be used to permit a small move-- It will be understood that ment of the driving structure to insure constant frictional engagement of the disk 23 with the driving wheel 17 or the rim 16 of the carriage.

Mounted within the gear box 25 is also a governor mechanism 29,

1 floor l2. The top floor 12 Y is opened, as shown-in -Fig. 1, and

,a support for a swing downward a slotted opening speed of rotation is insure In the present instance, the drive shaft 27 is fitted with a ulley 30 and a belt 31. This belt also em iraces a small driving pulley 32 mounted upon the armature shaft of the driving motor 33. The motor is supported upon the of the cabinet provides tone arm 34, whlch may swingin a plane tangent to the rim of the carriage 15 and thus pass across the plane face of phonographic disks. During the playing operation, the swinging movement of the tone arm will be produced by the tone grooves upon the record disk as they are traversed by the reproducing needle '35. When the phonograph is in non-playing condition, the tone arm is lifted and swung out of its contact with the record disk by means of a tone arm shifting lever 36 and to a position against a stop in 5. This lever may be swung vertically an is carried upon a pivot pin 37. The pivot pin in turn is fixed within a bracket 38 which is mounted upon the floor 12. The lever 36 is normally supported in its uppermost position by means of an operating lever 39, which is carried by the pin 37 and has a forwardly extending portion upon which a supporting pin 40 normally rests. The supporting pm 40 extends outwardly from the side of the lever 36 and overhangs this extension of the operating lever.

An examination of Fig.

in 40, the lever 36 may y under the influence of the weight of the tone arm 34 and as reaway from the sisted by the action of a bellows 41, which is connected with the end of the lever 36 by means of a link 42.

" Fastened upon the extension end of the operating lever 39. is a link 43 which pivotally depends therefrom and is formed with near its lower end, within which a pin 44 1s seated. This pin is carried by an oscillating lever 45 mounted upon a bracket 46 within the phonograph cabinet. The bracket carries a pivot shaft 47. by which the arm 45 is supported. Fixed upon this same pin is a catchmember 48, the hooked end of which is disposed .in the path of travel of carriage stop pins 48' and will be engaged thereby when the oscillating arm 45 is swung downwardly by the action of the operating member 39 and the.

movement of the link 43. The operating lever 39 is initially actuated by a lever 49 pivoted to the floor 12 and connected therewith by a shackle link 50. The opposite end of this lever is fastened by a draw rod 51 to'the plunger 52 of 'asolenoid 53. The electrical connections for this'solenoid will be hereinafter described.

by which uniform 2 will show that when this operating lever has been swung Cotiperating with the lever 39 is a bell crank 54 which is'provided to seat beneath the end of the lever after it .has been op 57. This magnet also actuates a swinginglever 58, mounted upon a pivot standard 59. The outer end of this swinging lever is in-' tended to normallysupport a knife switch blade 60 which is pivoted at 61, and under the influence of s ring 62, may be brought to re ister with t e contact finger 64, thus comp eting an electric circuit. The supporting end of the swinging. lever 58 is normally locked beneath the switch blade 60 by means of a catch 65. This catch is in realit the armature of magnet 66 and may e swung out of its obstructing position beneath the lever 58 by energization of this ma net. A spring 67 normally holds it in its ocking position. An auxiliar switch is provided for a purpose to be specified and consists of a switch blade 68 formed in the shape of a bell crank. One leg of this crank is adapted to stand in the path of travel of the carriage stop pins 48 and the other leg is designed to be brought into contact with a finger 69 by which the circuit will be completed. A spring 68' normally holds the switch blade and the finger out of engagement and is onl overcome by the pressure of the pin 48, t ereby completing a circuit through solenoid 53.

In order to automatically stop the phonograph at the end of the playing operation, a pair of spaced contact fingers 70 and 71 are provided. These fingers are carried by the reproducer of the phonograph or the tone arm, as convenience may dictate. At least one of these fingers is flexible so that the two may be brought together to complete a circuit by which the operation of the motor will be discontinued. These fingers will move into the path of travel of the disk fastening pin 21 as the tone arm swings inwardl and the swinging action of this pin will raw them together, thus producing the operation desired. 7,

In operation, the numeral 72 indicates a source of electric supply. This supply is normally represented by the current delivered for household use, which is constantly 110 volts. The lead wire 73 is fitted with a switch 74. This switch in turn is connected by a suitable conductor with a wire 75 leading to one pole of the solenoid coil 53 and wire 76, primarily connected with one pole of a transformer 77. This wire also has an extension 78 connecting with one of the brushes of the o erating motor 33. The other brush is fitte with a conductor 80 leading to a binding post 81 which is electricall connected with the switch blade 60. T e current then passes through the switch blade and the finger 64 to a conductor 82, thereafter connecting with a wire 83, which represents the opposite lead wire of the source of supply. The lead wire 83 also connects with the other incoming pole of the transformer 77 by means of an extension wire 84.

Briefly reviewing this wiring arrangement, it will be seen that a transformer circuit is established through the wires 76, 83 and 84 and a motor circuit is established throu h the wires 76, 78, 80, the switch blade 60 an its finger 64 and'return wires 82 and 83. These circuits will represent the potential of the feed wires. A current passing through the high voltage wire 75 will enter the coil of the solenoid 53 and will lead through a conductor 85. This conductor is connected with the contact member of a repeating switch 86, through the blade of which the current passes to a return conductor 87 The conductor 87 is directly connected with the wire 84, which is a continuation of the feed wire 83, thus completing -a high voltage circuit for the solenoid 53. The conductor 85 also communicates with a switch wire 88 fastened to one pole of the switch 68, through which switch the current will pass and thereafter flow along a return conductor 89 in communication with the wire 80. The remaining circuits are low voltage circuits and in the present instance represent approximately twenty-seven volts. Low voltage wire 90 leaves one of the outgoing poles of the transformer and passes to one end of the magnet coil 66, the other end of this coil being connected with a wire 91. The wire 91 leads to an operating switch 92' and conducts a current therethrough to a wire 92 which returns and is fastened to the opposite 0*tgoing pole of the transformer. Connected to the wire 90 is also a wire 93 which is in communication with one end of the coil of the magnet 57. The opposite end of this coil is fitted with a conductor 94 passing to one pole of a stop switch 95, the opposite pole of this switch being provided with a conductor 96 leading to the contact finger 71 upon the reproducer. A current may be completed through the contact finger 71 and the contact finger and may then pass along a wire 97 to unite with the wire 94 leading 'to the starting switch. The wire 96 is also fastened to the wire 92.

In starting the machine, switch 92' is closed. This completes-the circuit between the conductors 91 and 92; the circuit passing along the wire 92 from the transformer passes through the switch 92', then along the wire 91 and through the magnet 6", thereafter returning to the transformer along the conductor 90. This action will energize the magnet and cause it to influence the catch 65, thus swin ing it from beneath the switch blade 60. ue to gravity and the spring 62, the blade will fall and make contact with the finger 64. This contact will close the main motor circuit and complete this main circuit through the motor and the switch, as previously described. When this has taken place, the driving disk 32 will be placed in continuous operation and will act to rotate the carriage as it comes into frictional enga ement with the side of the carriage rim. is the carriage rotates in the direction of arrow a, as indicated in Fig. 2, the pin 48 will move into contact with the switch member 68, thus completing the circuit through this member and the switch finger 69. High voltage current will then pass from the source of supply through the conductor 7 5 to the solenoid 53, then passing along-the conductor to the conductor 88, through the switch blade 68 and the finger 69 to the conductor 80 and thence returning as described, to the source of supply. This action will, of course, energize the coil of the solenoid 53 and draw its core downwardly. This will swing the lever 49 in the direction of arrow 6 and act to swing the operating lever 39 in the direction of arrow 0. The forward extension of the actuating lever 39 will, of course, swing downwardly and from-its supporting position beneath the pin 40. This will leave the tone arm lever 36 unsupported and as it swings downwardly in the direction of arrow b, will lower the needle of the tone arm onto the record. The lowering of the tone arm will, of course, be retarded by the cushioning action of the bellows 41. Simultaneous with this operation, as instigated by the energization of the solenoid 53, the link 43 will press downwardly upon the oscillating lever 45 and swing the catch member 48 into the path of travel of the lock pins 48, thus temporarily locking the carriage against movement.

In the event that it is desired to repeat the selection played upon the record, the switch 86 is closed. It will be noted that the plunger of this switch is provided with an arm 86' which may also be brought to engage the knife of the switch 92. When the switch 86 is closed, the switch 92 will, of'

- closing the switch 86, the solenoid 53 will be actuated to permit the tone arm to again rest upon the record and repeat the selection, it having been previously restored to the transformer along conductor 90. This action releases the operating arm 39 from the supporting member 54 and allows the spring 55 to thrust the tone-arm lever 36 upwardly [and thereby swings the tone arm on its pivot and away from the disk. If the machine is to be stopped while in the course of playing a record, the switch 95 is closed."

This switch will complete a circuit from the transformer along the wire 92, throughwire 96 to the switch 95' and therethrough. returning along wire 94 to the coil of the solenoid 57 and then passing to the transformer along wires 93 and.90, as previously described,thus

allowing the arm 36 to be thrown upwardly before. the playing operation is complete. If it is desired to successively play the record rod 100 may be rotated. The lower end of this rod is fitted with a crank-extension which engages the upper end of the locking member 65 and when rotated will swing the catch 65 outwardly from its supporting position beneath the end of.lever 58 and thus will permit the switch-blade 60 to fall.

It will thus be seen that by the arrangement here disclosed, an automatically operated phonograph is provided for successively playing a series of records or repeatedly playing a single record.

Reference being had toFig. 1, it will be noted that the fastening members 21 are formed with two fingers integrally connectedv and preferably made from spring steel.

These fingers are adapted to yieldably grip the opposite sides of pins19 asthey' pass along .the grooves in the sides of these pins.

By this arrangement the fingers not only provide an adjustable fastener for disks of various thickness but provide an adjustable member for making contact between the two contact fingers carried by the reproducing mechanism. In this manner the position of the fasteners 21 may be made to bear a direct relation to the record grooves,-thus causing the discontinuance of the playing operation when the end of the record groove has been reached. 2
